8 Claims. (Cl. 128-283) This invention relates generally to colostomy and ileostomy appliances and specifically to a simplified appliance facilitating the use of a disposable flexible bag.

The invention herein disclosed is closely related to my copending U. S. application, S. N. 245,822, filed September 10, 1951, now Patent No. 2,721,553, and my previously issued U. S. Patent No. 2,684,675, granted July 27, 1954, and is believed to be an improvement over both of my earlier structures.

My present invention incorporates the advantages of both of my above identified inventions by combining the simplicity of the structure disclosed in said patent with the numerous advantages of the structure disclosed in said application.

it is an object of my present invention to provide a novel and improved colostomy appliance which is particularly adapted for inexpensive manufacture and facilitates the use of a disposable bag of thin sheet material and which can be quickly and easily removed from the supporting belt assembly to facilitate changing of the disposable bag unit.

it is another object of my present invention to provide a colostomy and ileostomy appliance incorporating a disposable inexpensive bag of thin sheet material with an opening formed therein to receive from the stoma of a wearer and provided with a pair of clamping elements surrounding said opening in tightly clamped sealed relation around the marginal edge portion thereof to permit adjustable attachment to the body of the wearer by a retaining ring adjustably mounted on one of said clamping elements.

It is still a further object to provide a device of the class described wherein the same may be adjustably mounted on the body of the wearer and securely retained in operative position by an easily removable belt mounting member which retains the belt assembly on the wearer even when the bag assembly has been removed therefrom.

It is still another object to provide a pair of clamping elements adapted to sealingly clamp a portion of a dis posable bag of thin waterproof sheet material therebe' tween with means for locking said elements in clamped together position with said bag and receiving a separate belt mounting member which can be easily and quickly removed therefrom to facilitate changing of the bag without removal of the belt assembly.

These and other objects and advantages of my invention will more fully appear from the following description made in connection with the accompanying drawings wherein like reference characters refer to the same or similar parts throughout the several views, and in which:

Fig. 1 is an exploded perspective view of my improved appliance;

Fig. 2 is a central vertical sectional view thereof;

Fig. 3 is a front elevational view showing one form of my new clamping ring;

States Patent 2,787,270 Patented Apr. 2, 1957 Fig. 4 is a front elevational view of my new device mounted on the body of a wearer;

Fig. 5 is a front elevational view of an alternative form of mounting ring and insert assembly;

Fig. 6 is a fragmentary vertical sectional view taken substantially along the line 6-6 of Fig. 5; and

Fig. 7 is a front elevational view of the bag per se.

As illustrated in the accompanying drawings I provide a flexible bag 10 made from any suitable thin waterproof sheet material such as polyethylene tubing which is sealingly closed across the upper end Illa thereof. One side of the bag 10 has an opening 10b formed therethrough and the lower end of the bag is open with a re silient roll 11 and spring clip 12 for closing the same.

It is obvious that the bag opening 10b must be rigidly reinforced therearound in order that the same may be tightly pressed against the body of the wearer to receive from a stoma therethrough and to eliminate possible leakage between the opening and the body of the wearer. In the form shown a pair of generally annular clamping elements 13 and 14 are provided for this purpose. The clamping element 13 constitutes a generally annular inwardly disposed insert ring which is positioned within the bag co-axially of the bag opening 10b as best shown in Fig. 2. This inner element or insert ring 113 is made from any suitable easily cleaned stifi material such as methyl methacrylate resin. This plastic type of material has been found to be more comfortable for the wearer than metallic rings or the like, but since the same is slightly yieldable and resilient, positive clamping means must be provided to securely interlock said elements 13 and 14. The outer clamping element 14 has a substantially cylindrical segment 14a extending outwardly from the inner periphery of an annular flange portion 14b. Said segment 14a is tapered from the outer free edge inwardly toward the annular portion of ring 14 and is of a diameter to tightly receive in sealed clamped relation the outer periphery of the insert member 13 with the portion of the bag surrounding the opening 10]) tightly interposed therebetween. The periphery of the insert 13 is tapered inwardly to cooperate with and be received in tightly registered relation within the slightly tapered segment 14a as best shown in Fig. 2. This taper, of course, limits the inward shifting movement of the insert relative to the retaining ring but due to the resiliency of the bag material and the smooth surface of the segment14a and the peripheral edge of the insert 13, some positive means for locking the two members in clamped position must be provided. One form of such locking device designated by the letter A, is illustrated in Figs. 1, 2 and 3, wherein three locking clips 15 are pivotally mounted in peripherally spaced relation on the annular flange portion 14b of element 14. These clips 15 may be swung outwardly into released position as shown by the dotted lines of Fig. 3 to permit the clamping ring 14 to be received over the insert element 13 when the same is positioned within the bag and thereafter said clips are swung into locking position to positively hold the insert mem her and retaining ring together. Each of said clips has an outstanding portion 15a which extends outwardly from the outer face of annular flange 14b approximately the same distance as the cylindrical segment and the retaining portion 15b of said clip is adapted to overlie the outer marginal edge portion of insert 13 as best shown in Fig. 2, and positively retain said insert in sealed clamping position. It should be noted that the three clips 14 are not equally spaced apart. This is clearly shown in Fig. 3. This is important to prevent downwardly directed pressure on the bag from causing the bag to tear by engagement thereof against the end portions of the two lower clips. By positioning the two lower'clips immediars /pro ately below the horizontal diameter of the clamping element 14, most of the downwardly directed pressure on the bag will be carried bythe upper periphery of the substantially cylindrical segment 14a and only an absolute minimum force will be on the portions of the bag engaged by the clamping portions 151; of said clips. The clips 15 are held in clamping position by small cooperating center punch depressions in said clip which are received in similar recesses in said flange 14b as best shown in Fig. 1. The upstanding portion 15a of each of said clips is disposed adjacent the outside surface of the segment 14a as best shown by the full line positions in Fig. 3 to provide a substantially cylindrical outer surface. After the two clamping elements 13 and 14 have been secured together into the position shown in Fig. 2, a belt mounting retaining ring 16 of annular shape receives the bag assembly therethrough and the inside diameter thereof is suflic'iently large to journal the outwardly extending flange 14a with the clips 15 closed thereagainst and permit adjustable rotational movement of the bag with respect to said retaining ring 16 in order to facilitate adjusting the angle at which the bag depends from the supporting retaining ring according to the comfort of the wearer and depending on whether the wearer is in prone position or in upright position. The retaining ring, of course, has a plurality of knobs 16a which are adapted to receive cooperating fasteners 17 of the two belts 18 as best shown in Fig. 4. In order to remove the bag assembly including the clamping rings 13 and 14 .from the retaining ring 16, the top of said retaining ring is pulled out away from the wearers body and said bag assembly pulled upwardly therethrough. After removal of the bag as sembly, said bag may be readily cleaned or replaced as desired by the wearer and returned to operative position without removal of the belts 18.

An alternative form of my clamping elements is illustrated in Figs. and 6 and is designated by the letter B. An annular mounting element 20, similar in all respects to mounting element 14 except that no clips are mounted thereon, is provided in form B of my invention. An insert member 21, similar in all respects to insert .13 except that said insert 21 is provided with eccentrically mounted locking cams 21a journaled on the inner surface thereof.

Retaining engagement with the inside surface of the annular flange of clamping element 20 around the inner periphery thereof to cooperate with the tapered vfit between elements 20 and 21 and positively prevent relative movement therebetween. Th clips 15 in form .A of my invention are mounted on the outside of flange ring 14b and engage the outer edge portion of the insert 13 while the eccentric locks 21a are mounted on the inside surface of the insert member 21 and engage in inside surface of the flange of clamping element 20 as best shown in Fig. 6.

It will be seen that I have provided a relatively simple yethig'hly efiicient colostomy appliance particularly adapted for inexpensive construction and to facilitate use of a disposable bag made of thin flexible sheet material. The clamping elements 13 and M of form A of my invention and clamping elements 20 and '21 of form '13 of my invention positively clamp in sealed relation the portion of one layer of the bag it! surrounding the opening 1% to form an easily handled, substantially unitary bag assembly which is conveniently retained on the body of the wearer by the ring 16 which journals said assembly and permits adjustment of the angle .at which the bag depends therefrom, the belts 18 securely anchor the ring 16 in the desired position on the body of the wearer. As has been previously stated, the entire bag assembly may be easily and quickly removed from the retaining ring 16 and supporting belt structure for cleaning and replacing of the bag. In form .A of my invention, the clips 15 may be easily and quickly shifted into releasing position without requiring the use of any special tools, however,

the eccentric elements 21a of form B of my invention are slotted and obviously require the use of a small turning element such as a dime or screw driver to supply the necessary turning leverage. The insert member is providtid with an inwardly extending circular bead designated in form A of my invention as 13a and in form B of my invention as 21!) which forms a groove respectively designated by the reference characters 13b and 21c of said insert members 13 and 21 which groove is adapted to receive and retain a beaded sleeve (not shown) such as the sleeve 22 disclosed in my Patent No. 2,684,676, issued July 27, 1954. It should be noted that this sleeve may be used either with or without the cementing disc 19 shown in said patent. It is obvious that the present invention is greatly simplified in construction and use with relation to my previously identified copending application while incorporating all of the advantages thereof.

It will, of course, be understood that various changes may be made in the form, details, arrangement, and .proportions of the parts without departing from the scope of my invention which generally stated consists in the matter set forth in the appended claims.
